OUTLINING-TOOL.

spammer-trier; forming pm of Letters Patent No. 353,077, dated November 23,1886.

Application filed June 10, 1856.

.To all whom, z5 Zai/ty concern.-

Be it known that l, ROBERT A. MACKENZIE, of the city, county, and State of New York, have invented a new and Improved Outliniug- Tool, of which vthe following is a full, clear, and exact description.

My invention relates to an outlining device designed particularly for carpenters use in the work of dressing doors and similar pieces of stuff to their frames,whereby a perfect fit may be obtained without the necessity of4 frequently setting the door up in the frame to testthe same as the work proceeds.

The invention consists of the outlining device constructed, combined, aud operated as hereinafter described and claimed.

`Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a reduced side elevation of my invention, showing its sectional construction. Fig. 2 is a reduced edge view of' the saine.

` Fig. 3 is an enlarged side view of the device,

parts being broken away to show its construction, and Fig. 4 is a broken edge view..

The outliningtool is by preference made in several sections, a, adapted to be connected together end to end by any suitable means. Each section is complete in itself, so when detached from the other sections it may be used as ashort outlining-tool. I prefer to join the sections by means of a right and left hand screw-bolt, b, adapted to screw into nuts c c, fitted in the sections, the bolt being formed orY provided with a central nut,'b, formed with orifice in which a small rod may be placed to act as a lever to facilitate the turning of the bolt. The sections a are duplicates'ofeach other, and each section has several chambers, d, formed in one of its straight edges. In each charnberd is placed a coiled spring, e, preferably placed upon a short spindle, 'f, to prevent torsion of the spring. Upon or ver each spring e is placed, in each chamber d, a plunger, g, preferably in the form of a tube plugged at its outer end.

Secured upon theledgc of each section ais a* metal plate, h, having formed in it as many 5o openings, i, as there are plungers g, and the plate h is adapted to be moved longitudinally,

the chambers d against the pressure of the springs e, and, secondly, for releasing said plungers, so the springs e may force them outward through the openings i. The plates h are by preference held to the edge of each section a by dovetailed plates k k2, held in dovetailed slots k in the plate by screws Z Z', passed through the plates k czand screwed, some into the material of the section, others into the frictionblocksn, below described. VThe plate h of each'section may be moved longitudinally by a small rod or bar inserted in an ortice, m, made in the plate, a recess, m', being formed in the side of the section for the insertion of When the plates h are moved to release the plungers g, so that they will be forced outward by the springs f in order to grasp the tubes for holding them from being forced entirely out of the chambers d by the springs i, I provide a friction-block, n, (above mentioned,) for each tube, placed ina cavity, o, made in the edge of the sect-ions.A Each friction-block n is forced toward its tube d by a coiled spring, p, and when the tubes are held in their chambers cl the blocks n are held in contact with the tubes by the action of the tionblocks u are moved by the movement of the plate back away from the tubes, so they vare left entirely free to the action of the springs e. The movement of theplate h effects the movement of the blocks n through the medium of the small plates k2 and screws l', which latter enter the friction-blocks, as shown in Fig. 3. The friction-blocks are held in place in the cavities o by the screws q q, which pass through the countersunk slots q' made in the blocks and screw into the material of the sections a.

ln use the pluugers g will all be forced into their chambers and the plates It move to hold them within the chambers. Then the edge of the tool will be placed upon thesurface of the frame or other objects whose outline it is de x IOO permit the friction-blocks n to press upon the tubes and hold them firmly in the positions l they occupy. The tool now being removed from contact with the surface, the outer ends of the tubes q will give theexact outline of the surface, which can be easily transcribed to a door, panel, frame, or any object,so the saine can be easily dressed to match.

My invention is applicable to many uses, but in fitting doors to their frames it is particularly useful.

Having thus described my invention, what I claim as new, and desire to secure by Letters e, plungers g, and the apertured sliding plate h, held at the edge of the section and arranged to release all of the plungers simultaneously, substantially as and for the purposes set forth.

3. The sections a, formed with Achambers d at right angles with the chambers d, incombination with the plungers g and springs e, placed in the chambers d, for forcing the plungers outward, and the sliding plate l1, arranged to retain the plungers, substantially as described.

4. The several sectionsa, provided with means for connecting them together end to end, in combination with the sliding plates l1, at the edges of the sections, and having apertures fi, the spring-actuated plungers g, placed in the chambers d, and the spring-actuated friction-blocks n, arranged topress against the plungers g, substantially as and for the purpose set forth.
